Chicago police said around 5:18 p.m. the victims — a woman, 35, and two men, 29 and 23 — were on the sidewalk in the 3400 block of West Ogden Avenue in North Lawndale when a vehicle pulled up and two armed people from inside got out and shot at all three victims.

The suspects then got back in the vehicle and fled heading westbound.

The 29-year-old man was shot in the chest and was taken to Stroger Hospital, where he was pronounced dead.

The 23-year-old man was hit in the stomach and was taken to Mount Sinai Hospital in critical condition.

The 35-year-old woman suffered a gunshot wound to the left leg and was taken to Mount Sinai Hospital in good condition.

The 2-alarm fire sent smoke billowing into the sky as flames shot out from an auto repair shop in the 12800 block of South Western Avenue.

It is unclear if anyone was inside or if there were any injuries. 

The Red Cross has been contacted to help at least one family. 

There's no word on what started the fire.

CBS News Chicago reached out to the Blue Island Fire Department for more information.

Many are proving this election is important to them, with some voters waiting hours to cast their ballots.

"I think almost an hour, yeah, it feels like it's been several."

For Beatrice Moxon and Reena Shenoy, they say they had no other choice if they wanted to vote.

An hour and a half is how long people have been waiting just to get inside this Lakeview supersite on Halloween.

While some voters have waited 90 minutes, election judges at the Lakeview Supersite say there's been lines around the block all week and at times some have waited up to four hours.

It all comes as politicians and candidates were out across Chicago Saturday encouraging people to get out and vote — including Gov. JB Pritzker, who attended an event at a West Side church.

"Vote ... vote, vote, vote because Donald Trump is trying to take away your right to vote," he said.

So far, the Chicago Board of Elections says as of Friday, 235,000 people voted early at the polls or with mail-in ballots.

Northwestern University professor Tabitha Bonilla says that's about 15% of the vote submitted — which is 11% more voters than the last midterm election in 2022. Overall, she says Chicago is 30% ahead of the turnout four years ago. 

Why such a turnout?

"We have an economy that is struggling, there is a war in Iran, and people are really unhappy with Donald Trump as things are," Bonilla said.

Another important issue, according to Bonilla, is immigration arrests in Chicago and surrounding suburbs in the last two years since President Trump took office.

"I have heard a couple of neighbors and people in the grocery store this morning about how they are excited to vote to show that they are upset with that particular incident in mind."

"I think both parties have pushed early voting and vote by mail by a far greater degree," said Kevin Coyne, chairman of DuPage County GOP.

Coyne says well over 100,000 voters have shown up to the polls there. While the county has seen a blue wave in recent years, he says this election has the potential to turn it back to red.

"We are expecting those county races to be very close again this year. The sheriff race, the treasurer's race in particular — those could easily be one-point races."

The League of Women Voters of Chicago says high early voting numbers can be attributed to young people at the polls.

The Chicago Urban League and Chicago Vote held a rally Saturday morning and marched to the polls to encourage voters between 18 and 35 to exercise their civic duty.

"You can't say you want change in your city and community and you're not voting," said Alexx Brown with the Metropolitan board of the Chicago Urban League.

CBS News Chicago reached out to the office of Pritzker's opponent, Darren Bailey, to see if he was holding any events on Saturday, but did not hear back. 

The ages of the victims range from 15 to 46, according to police.

Shootings from Friday

In the first shooting of the weekend, officers responded to a call of a walk-in person shot at Stroger Hospital.

Upon arrival, officers spoke with the victim, a 46-year-old man, who suffered a gunshot wound to the right thigh just before 9:30 p.m. in the 5400 block of West Van Buran Street. He is listed in good condition.

The victim couldn't provide responding officers with further details about the incident. 

Later in the evening, just before 11:30 p.m., a 35-year-old man was shot and killed after an argument turned into a fight at a home in the 4800 block of North Kilpatrick Avenue.

Police said the victim and a known man were involved in the argument that turned into a fight. During this, the known man pulled out a gun and fired shots, hitting the victim in the head.

He was taken to the hospital, where he was pronounced dead.

Police said a person of interest is in custody and a firearm was recovered.

In other shootings from 5 p.m. Friday to 5 a.m. Monday:

Shootings from Saturday

• At 12:23 a.m. in the 500 block of East 50th Place, officers responded to a call about persons shot. Upon arrival, officers found a 19-year-old man and a 15-year-old boy, both with gunshot wounds. The 19-year-old was shot in the head and was taken to the University of Chicago Hospital in critical condition. The 15-year-old was shot in the stomach and was transported to Comer Children's Hospital in critical condition. No additional injuries were reported. 
• At 5:18 p.m. in the 3400 block of West Ogden Avenue, a 29-year-old man, a 23-year-old man and a 35-year-old woman were all on the sidewalk when an unknown vehicle pulled up alongside. Two suspects got out armed with guns and shot at the victims before fleeing in the vehicle westbound on Ogden. The 29-year-old was shot in the chest and was taken to Stroger Hospital, where he was pronounced dead. The 23-year-old victim was shot in the stomach and was taken to Mount Sinai Hospital in critical condition. The 35-year-old victim was shot in the left leg and was taken to Mount Sinai Hospital in good condition.

Raiola made his second straight start for the Ducks (5-3, 3-2 Big Ten) with Dante Moore ruled out for the season.

After Oregon running back Jordon Davison left the game with an injury in the first half, freshman Brandon Smith led the comeback with 82 yards rushing and scored the go-ahead touchdown in the fourth quarter.

Aidan Chiles was 22 of 38 for 281 yards and a touchdown for Northwestern (6-2, 3-2). He ran for 93 yards and another TD late in the second quarter, his 10th of the season.

Northwestern had a 10-0 first-quarter lead was up 20-13 at the half after Raiola's 10-yard touchdown pass to Dakorien Moore with 49 seconds remaining. Raiola hit Moore again in the fourth quarter on a 75-yard strike, with Moore finishing with 128 yards the two TDs.

Raiola found Jamari Johnson was a 17-yard touchdown pass, and Smith rushed for a 2-yard touchdown on fourth-and-goal to put Oregon ahead for the first time, 27-23, in the fourth quarter before Moore's second touchdown sealed the game.

Elias Lindholm scored in overtime as the Bruins rallied from a two-goal deficit in the third period to top the Chicago Blackhawks 5-4 and extend Boston's home winning streak to five games.

Mason Lohrei scored to pull Boston within a goal and Morgan Geekie's second goal of the season with 12 seconds left in the third period sent the game into overtime.

Ryan Greene and Connor Bedard scored in the third period as the Chicago Blackhawks took a 4-2 lead. Anton Frondell had his second career two-goal game for Chicago.

The Blackhawks came into the game with the worst power play in the NHL, converting on 4 of 40 opportunities and were 0 for 11 on the power play on the road. However, it took Frondell just 11 seconds to give Chicago the lead after Will Borgen was whistled for a delay-of-game penalty.

Goaltender Michael DiPietro kept Boston in the game with key saves as the Bruins were outshot 28-13 in the first two periods. He stopped a Bedard shot from the slot with 2:09 left in the first period. Geekie, who hasn't scored in his previous nine games, hit a shot off the post late in the first period.

David Pastrnak scored on a breakaway in the first period for his 428th career goal, passing Patrice Bergeron and moving into sole possession of third place on the Bruins' career goal-scoring list. Casey Mittelstadt and Mason Lohrei also scored for the Bruins.

Frondell redirected Tyler Bertuzzi's wrist shot from the point past a surprised DiPietro early in the second period for his second career two-goal game. DiPietro, coming off his first career NHL shutout, kept it a one-goal game with a point-blank save of 500-goal scorer Patrick Kane midway through the second period. The Bruins tied the game when Mittelstadt took a feed from James Hagen and snapped a shot past Arvid Soderblom.

James finished with nine carries for 107 yards. Jonaz Walton added a 3-yard touchdown run, and Jerome Bettis Jr. had a 31-yard TD catch for the Fighting Irish (7-1), who successfully bounced back after their road loss at BYU two weeks ago. Notre Dame finished with 426 yards, its fifth time amassing 400-plus yards this season.

Quarterback Jackson Gutierrez rushed 28 times for 110 yards for the Midshipmen (2-6), who haven't won a game in the long-running series since 2016.

It was also the second straight loss for Navy in neutral site games played at Gillette Stadium, home to the NFL's New England Patriots. The Midshipmen also lost to Army in Foxborough in their 2023 meeting.

Leading 14-13 at halftime, Notre Dame scored on each of its first three possessions of the second half to take control.

Notre Dame's defense came in allowing only 67.3 yards per game on the ground. Gutierrez surpassed that in the second quarter.

It helped the Midshipmen, who entered as 29.5-point underdogs, both to eat up the clock and keep the ball out of the Notre Dame offense's hands. The Irish had only three possessions in the half, holding the ball for a scant 6:27.

But after Navy took a 13-7 lead on Gutierrez's 2-yard TD run with 1:52 to play in the first half, the Irish needed only 50 seconds to jump back in front via Nolan James Jr.'s 52-yard touchdown run.

The Irish had the ball first after halftime and moved quickly, increasing their edge to 21-13 after Walton punctuated a 78-yard drive with a 3-yard TD run. Following a Navy punt, James' second touchdown pushed the lead 28-13.

The Takeaway

It took a while for the Irish's defense to handle the nuances of Navy's multifaceted, hybrid option-spread attack coming off their bye last week. But it could also serve as a needed jolt for a unit that will need to be at its best with next week's matchup against top-ranked Miami looming.

Fresh off a win over Oregon, the Illini struggled for most of the game against Maryland despite quarterback Katin Houser's return from a hand injury. They finally took their first lead on Javari Barnett's 64-yard touchdown run on the first play of the fourth quarter, which made it 17-14.

Maryland (3-5, 0-5 Big Ten) tied it with a field goal, but Illinois mounted one more scoring drive after taking over at its own 26 with 5:45 to play.

The Illini (5-3, 3-2) were able to drive deep into Maryland territory and then run the clock down after the Terps had exhausted all their timeouts.

Quarterback Malik Washington and running back DeJuan Williams both turned the ball over for Maryland, but they also had touchdown runs in the Terrapins' first game under interim coach Aazaar Abdul-Rahim. Maryland has lost six straight, a skid that brought an end to Michael Locksley's tenure.

Washington opened the scoring with an 8-yard touchdown run in the first quarter. Houser, who threw an early interception, rebounded with a 16-yard scoring strike to Brayden Trimble with 27 seconds left in the half that made it 7-all.

Williams put Maryland up 14-7 with a 17-yard touchdown in the third quarter.

The takeaway

Illinois: The Illini have struggled to put away struggling teams like Michigan State and Maryland, but Illinois now has three straight wins and its QB is back.

Maryland: The defense looked inspired after Abdul-Rahim was promoted from the defensive staff to interim coach. But the Terps couldn't get the stop they needed on the final drive.

Illinois: Hosts Nebraska on Friday night.

Maryland: At Purdue next Saturday.

Timothy Lee, 39, from Chicago, is charged with felony vehicular hijacking, attempted vehicular hijacking, and unlawful vehicular invasion. He was also charged with two misdemeanor counts of resisting a peace officer.

Police say on Thursday afternoon, Lee allegedly tried to steal a car in the 2300 block of North Lister Avenue. 

It was further alleged that he then went to a car wash in the 2100 block of West Fullerton Avenue, where he got into a woman's parked car, demanded she get out, and drove away.

Police arrested Lee early Friday morning.

He was scheduled to appear in court for a detention hearing on Saturday.

Here's what to know about what's formally known as daylight saving time as it ends for the year:

What is daylight saving time, and why do we have it?

Daylight saving time is the period during the year, from March to early November, when the majority of the U.S. operates one hour ahead of standard time.

The move effectively "saves" an hour of daylight from the morning and adds it to the evening during the spring and summer months when the days are the longest. In the fall and winter months, when the days are shorter, the U.S. returns to standard time, with daylight coming earlier in the morning.

For example, in Boston on Saturday, before the time change, the sun will rise at 7:16 a.m. and set at 5:39 p.m., according to the National Weather Service. On Sunday, back on standard time, sunrise will be at 6:17 a.m. and sunset will be at 4:37 p.m.

The U.S. first adopted daylight saving time in 1918 during World War I as an effort to conserve fuel after Europe implemented its own time change, according to the Congressional Research Service. After the war, Congress repealed the clock switch but gave states the option to continue observing it.

During World War II and the 1970s energy crisis, Congress brought year-round daylight saving time to the U.S., again with the goal of reducing energy consumption. These experiments didn't last long.

After the war, the U.S. let states and municipalities decide for themselves if they wanted to keep daylight saving time and when to observe it. (Congress didn't establish a uniform start and end for the time change until 1966.) In the '70s, continuous daylight saving time was stopped before reaching the 10-month mark.

Will the U.S. move to year-round daylight saving time?

Earlier this year, legislation to once again make daylight saving time last all year long cleared a major hurdle in Congress. The bill, called the Sunshine Protection Act, passed the House in July and went to the Senate. The legislation would also let states opt out of daylight saving time altogether before the law takes effect.

President Trump, who supports the bill, accused a fellow Republican, Arkansas Sen. Tom Cotton, of holding up the legislation. Mr. Trump even posted to social media what he said was Cotton's cellphone number and urged people to call the senator to express their support for the measure.

In response, Cotton noted Congress has tried permanent daylight saving time before, only to go back to the twice-yearly time change "once Americans experienced absurdly late sunrises in the winter."

There is a ticking clock for the Senate to take action on the bill. The legislation and any other bills awaiting approval in Congress are set to expire in early January when the new class of lawmakers elected in Tuesday's midterm elections takes office.

If the bill does die, the effort to change daylight saving time will have to start over and be approved by the House and the Senate before it can go to the president.

Did the time change today?

The time won't change until Sunday.

For 2026, the end of daylight saving time comes during the overnight hours after Halloween, giving revelers an extra hour of enjoying late-night costume parties — or an extra hour of sleep to recover from their fun.

But for parents of young children, the time change can be more of a trick and less of a treat, potentially disrupting their kids' sleep schedules until they adjust.

What day and time does daylight saving time end in November 2026?

Daylight saving time officially ends at 2 a.m. local time on Sunday, Nov. 1.

Americans have been "falling back" on the first Sunday of November since 2007, when the most recent changes to daylight saving time took effect. A 2005 law moved the end date from the last Sunday of October.

Do we lose or gain an hour when daylight saving time ends?

Most Americans will gain an hour when daylight saving time ends, making up for the hour they lost when the clocks "sprang forward" in March.

When will daylight saving time start again in 2027?

Daylight saving time is set to begin in 2027 on Sunday, March 14, at 2 a.m. local time. The time change starts on the second Sunday of March, which falls on such a late date next year because the month starts on a Monday. In 2026, daylight saving time started on March 8.

The start date was also changed in 2007 to extend the length of daylight saving time, which previously began on the first Sunday of April.

Which states don't do daylight saving time?

Daylight saving time is observed in every state except for Hawaii and most of Arizona. The Navajo Nation, which is located in part of Arizona, observes the time change to stay on the same time as their communities in the neighboring states of New Mexico and Utah, according to the tribe.

The U.S. territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands also don't observe daylight saving time.

Will my phone change for daylight saving time automatically?

Phones should change overnight to display the correct time if they're set to update automatically.

Apple, Google and Samsung have support pages with instructions for changing the clocks on their devices. Carriers like Simple Mobile and Straight Talk have also posted steps online for checking the settings on other phones.

Evanston police said Ernest W. Pentek, 48, of Chicago, was charged with 14 felonies, including four counts of unlawful possession of a firearm by a felon, one count of aggravated unlawful possession of a weapon involving a shotgun with a barrel less than 18 inches, one count of possession of methamphetamine with intent to deliver, one count of possession of methamphetamine, four counts of unlawful possession of a controlled substance, one count of possession of a controlled substance with intent to deliver, one count of possession of cannabis with intent to deliver, and one count of possession of cannabis.

Evanston police said an investigation was carried out by its Special Operations Group and developed information that Pentek was allegedly distributing narcotics in the Evanston and Chicago areas.

Investigators also received information indicating that Pentek possessed multiple guns and potentially dangerous incendiary devices, the department said.

According to the department, officers gathered additional evidence and obtained a search warrant for Pentek's home in the 6900 block of North Ashland Avenue in the Rogers Park neighborhood.

The Special Operations Group, along with Evanston Police Department's Special Response Team and the Cook County Sheriff's Police Bomb Squad, executed the search warrant around 2 p.m. on Friday. Pentek was taken into custody without incident.

Officers recovered four firearms, an airsoft rifle, more than 500 grams of suspected methamphetamine, 7.1 grams of suspected heroin, 11 grams of suspected Xanax, 4 grams of suspected crack cocaine, 39 suspected MDMA pills, and approximately 2.6 pounds of suspected cannabis during the search of Pentek's home. 

The department said officers also recovered a substance believed to be Gamma-Hydroxybutyrate (GHB), $1,185 in U.S. currency, ballistic protective equipment, and several suspected homemade incendiary devices.

Pentek is scheduled to appear in court in Chicago on Saturday.

Chicago police said the victim was arguing with the known man inside the home just before 11:30 p.m. in the 4800 block of Kilpatrick Avenue in the Albany Park neighborhood.

The argument turned into a fight, and the known man pulled out a gun and fired shots, hitting the victim in the head.

The victim was taken to Lutheran General Hospital, where he was pronounced dead.

Police said a person of interest is in custody and a firearm was recovered.

No other injuries were reported.

Area 5 detectives are investigating.

It happened around 9:40 p.m. in the 2700 block of West Madison Street in the Garfield Park neighborhood.

According to Chicago police, the bus was traveling westbound on Madison Street when a CTA employee said he heard a loud noise coming from outside the bus and was then notified that a window on the bus had multiple bullet holes.

No one was hurt.

Area 3 detectives are investigating. 

With the family still looking for answers, they fear police are dropping the ball.

"Niko is a phenomenal person. He would have dropped anything at the drop of a dime just to come help you," said Fabian Fuentes.

He describes his 33-year-old brother, Niko Fuentes, as a family man — father to a young daughter, Skylar, and son, Niko Jr.

Family says Niko's kids and wife are still grieving. They were not in attendance with other family and friends canvassing the area of South Oketo Avenue Tuesday night, where he was found shot and killed in September.

"They are going to miss out on memories that they had or could have had all because someone decided to shoot him in the back," Fabian said.

Niko's loved ones went door to door begging neighbors for any photos, video footage, or any evidence of his killer.

Fabian said officers found his brother shot in the torso and killed around 3 a.m. on Monday, Sept. 28. The medical examiner concluded his death was a homicide.

"He wasn't about any gangs, not a bad head on his shoulder."

His family says they decided to call a press conference after they stopped hearing back from Bridgeview police about the investigation.

"Every time you try to reach out, there is never an answer, never a response, never information to provide for our family," Fabian said.

Meanwhile, others are nervous anyone could be the next victim.

"Isn't Bridgeview concerned that something like this could happen at any time of the day?" said Carol Gonzalez Krawczyk. 

The shooting happened in a quiet residential area, across the street from a park and a block away from Bridgeview Elementary School.

"If I lived here, I would be concerned, even more concerned. Now, I would be afraid to walk in the dark," Krawczyk said. "You have a killer in Bridgeview, and you need to find him."

As Niko's family and friends continue to lean on each other, they say they are fearful this could become another cold case and want potential witnesses to come forward with leads.

"For anybody that's been too scared to speak up, don't be. Don't be. It's ok to talk," Fabian said.

Bridgeview police are investigating. 

Community activists are offering a $3,000 reward for information leading to an arrest.

Longtime physicians worry about what it will mean for expectant mothers and their babies.

Dr. Joy West has likely delivered her last baby as chair of the OBGYN department at Roseland Community Hospital, where she's worked for more than two decades 

"It's a huge loss for the community. It's a personal loss to all of us. We're devastated. We did not see this coming," she said.

Saturday night, the labor and delivery unit will close. When the hospital announced earlier this month that the unit would be shut down, officials cited declining birth rates and financial constraints. The hospital's CEO said fewer than 50 babies were on track to be delivered there by the end of the year.

"It means another maternal healthcare desert in the city of Chicago. It means moms feel like they're not being prioritized," West said.

The South and Midwest regions of the U.S. have the greatest proportion of counties designated as maternity care deserts, meaning there's no obstetric clinicians or birthing facilities, according to March of Dimes.

Prime Healthcare also recently ended obstetrics services at three Chicago area hospitals: St. Joseph Medical Center in Joliet, Mercy Medical Center in Aurora, and Resurrection Medical Center in Chicago's Norwood Park neighborhood.

"I'm fearful that the persistently elevated rate of moms – Black and Brown moms, mainly – dying in childbirth will continue to elevate," West said.

After Saturday, expectant mothers who come into the Roseland emergency room with complications will be transferred to other hospitals. The closest labor and delivery unit is four miles away, or a 20-minute drive, at Advocate Trinity Hospital, which is also closing its obstetrics unit next year.

"The moms in this community deserve the same level of care as any mom in the Gold Coast or any place in the world," West said.

Some doctors and nurses in the OBGYN department at Roseland will find jobs at other hospitals or new roles here at Roseland, while some will retire.

About 7,000 people entered the Paul VI audience hall inside the Vatican on Saturday after a special private Mass in St. Peter's Basilica.

Leo, who is an avid tennis player and sports fan, said sports bring people together and can promote values such as fraternity, solidarity and peace.

"By acting as a concrete means of bringing people together, athletics can teach the values of cooperation and mutual sharing.  This is increasingly necessary in an age marked by the distance that can be created by technology," he said, according to Vatican News.

The teams are in Rome for the U.S. college basketball season opener on Sunday — an event dubbed the Eternal City Tip-Off and created to honor the U.S.-born pope. The universities' men's and women's teams will play a doubleheader at the Palazzo Dello Sport, an 11,000-seat arena about a half-hour drive from the Vatican.

Leo, who is currently recovering from lung cancer surgery, graduated from Villanova in 1977 with a Bachelor of Science in mathematics.

"Growing up on the south side of Chicago, we oftentimes heard, 'Go Irish.' But as you all know, Prevost graduated from Villanova! So, the Pope doesn't take sides. Prevost has another opinion, but we won't do that now," Leo joked during the audience, according to Vatican News.

Leo urged the teams and their families to embrace sports as a way to grow in saintliness.

"No one is born a champion, just as no one is born a saint," he said.

He warned against letting sporting rivalries get out of hand and he said he hoped the fans in Rome this weekend would actually get to know one another as they cheer, "even passionately."

"In any competition, the members of two teams, even when they have a competitive rivalry, are certainly not enemies," he said. "I hope, therefore, that despite the competitive nature of college basketball, there will be opportunities for the players and the fans of both teams to get to know each other in your days here in Rome."

Before the audience, the Rev. Robert Dowd, president of Notre Dame, acknowledged Villanova had something of an edge considering it counts the pope as an alumnus. But in an interview Saturday, he said the occasion to bring both teams together with all their fans in Rome for a papal audience and season opener was "amazing."

"That could be a little challenging, but I know that the pope is a pope for all of us, and so I'm grateful," he said. "I know in a particular way the pope talks about the importance of bridge building, and I'm sure he'll be a bridge builder when we play each other."

Philadelphia Archbishop Nelson Perez celebrated a private Mass for traveling fans in St. Peter's Basilica on Saturday morning, and asked the thousands of people in the pews to give a round of applause to the players. The English-language liturgy was unusual in that it had all the trappings of a papal Mass celebrated at the main altar and televised live by Vatican Media.

Asked about the upcoming games on the papal plane during a recent trip to France, Leo said, "They tell me that the people coming to the match, 90% are Villanova and 10% Notre Dame, so the voice of the people of God will be very strong on the Villanova side."

Leo is an avid Chicago White Sox fan and has been known to follow basketball, too.

"He will know who they (the players) are. He's a true, blue Villanovan," said the Rev. Rob Hagan, Villanova's longtime team chaplain. He said Leo used to attend Villanova games at the Palestra, the Philadelphia arena known as "The Cathedral of College Basketball."

Sunday's games coincide with All Saints' Day, a major Catholic holiday.

"Our true goal, beyond emerging victorious in any one event, is to win the prize of everlasting life," Leo said.

The nearly two-pound meteorite was found in Mali. It was named Teghaza 001, after the salt plain where it was discovered, NASA said in a news release.  

Study of the meteorite allowed NASA scientists to determine it was one of roughly 435 from Mars. Meteorites can be verified as having been part of Mars by comparing their chemical and mineral makeup to samples and data collected by NASA's Martian missions. 

Age-dating of the meteorite led researchers to conclude it was about 4.1 billion years old, making it one of the three most ancient Martian meteorites found on Earth, NASA said. That provides "a rare snapshot" of the planet's crust and formation, the agency said. 

"It was only after we started looking closely that we realized this meteorite is really unique," said Yang Liu, the lead author of a paper detailing the age-dating process and related discoveries. Liu is part of NASA's Jet Propulsion Laboratory in Southern California. "One of the paper's reviewers called it a Rosetta Stone for Mars." 

Previous ancient Martian meteorites provided narrower glimpses into the planet's history. But Teghaza 001 shows how Mars' crust formed from cooling magma and was then changed by water on the planet's surface. 

The meteorite is made of a unique mix of volcanic minerals, including zircon crystals, NASA said, matching samples observed by the agency's Mars Reconnaissance Orbiter in the planet's southern highlands. Francis Tissot, a geochemistry professor at Caltech, helped the researchers use a pioneering age-dating method that studied a piece of meteorite smaller than a fingernail. The precise method allowed scientists to analyze single grains of minerals. 

That analysis showed the rock had been altered by Martian water about 4.1 billion years ago. The rock itself may have been formed even earlier, NASA said. The data also showed that early Mars may have had a more dynamic water cycle than scientists previously believed.  

Paper author Lee Saper said that the meteorite "records interactions of water and rock and maybe even an imprint of the Martian atmosphere as it was losing water." Another study of the meteorite, published in June, focused on the rock's water content and considered how water might have shaped the early topography of Mars. 

"This is really our first piece of Martian crust from a part of Mars we've never had a sample of before," Lee, a scientist at NASA's Ames Research Center, added.

Liu said that further research on the meteorite is likely. 

"We've only scratched the surface," Liu said.
